DRINKING-CUP.

Specification of Letters Patent.

Patented Apr. 1th

Application filed April 27, 1914. Serial No. 834,578.

To all whom may concern Be it known that l, Jens EDWARD SHER- MAN, of orcester, in the county of forceshe and State of Massachusetts, a citizen of the United States have invented a. new and useful Improvement in Drinking-Cups, of which the following is a specification.

Many varieties of paper drinking cups have been constructed and are now in use, but with the exception of the cups molded in the shape of small tumblers and which are usually made of paper treated with some waterproofing preparation, the cups of which applicant has knowledge are very inconvenient to use. They present a sharp edge to the lips which is apt to cut them. They are wider at the mouth than at the base so that in drinking from them the water is apt to run out from either side of the portion resting on the lips. thus wetting the drinker and his clothes. ll-lloreover, there is no place to accommodate the upper lip.

ln my drinking cup below described these faults are corrected. the cup being deep and narrow. having a place to acconnnodate the upper lip when drinking, means for readily opening the cup and for preventing the lip from being cut while the cup is in use. lllOI'tOYGl', it can be folded flat for trans bortation and in this forni is of substantially uniform thickness.

irloreover. it has been found that a cup made of ordinary paper will hold water for a sullicient length of time so that a waxed or other especially prepared paper is unnecessary except where the cup is to be preserved, and the preservation of the cup is a thing; not desired.

My invention will he understood by ret erence to the drawings, in which llig'ure l is. a top view of the cup;

Fig". 2 being a side elevation of the cup when open for use. and

ll ig. 3 a vertical section of the cup. in closed position.

The cup is tubular, is closed at one end and comprises an under side it and an upper side i, The edge ot the side 13, which forms part of the opening or mouth, is cut down a at B so that it is of less height at its middle portion than the side it. The curve ot this dowinvard cut is such as to leave at each end portions Z) of substantially same length as tl adjacent edge of the under side it. These portions 25 serve as the side walls of a trough formed by the edge a when the cup is in use and prevent the water from trickling out at the ends of the drinking edge. The middle portion of the cut, '5. c., that between the portions is shaped to form a recess which will tit over the upper lip. The corresponding edge of the side it has a reinforce it which is folded over and turned down inside the cup and preferably is scaled against the inside wall of the side it, thus forming: a double edge a which extends along the entire upper portion of the side A, or at least so much thereor as would naturally touch the lips while drinking.

This cup may be constructed in a variety of ways, but as shown it is formed of a folded blank, the central portion of which forms the side A and carries the reinforce A the side portions being cut to term the recess B and folded to overlap as at Z) and i being stuck together. While the sealing of the portion A against the inner wall ot' the side It IS desirable, 1t isnot necessary, and in tact this portion may be turned outside the part A'and sealed thereto it thought best. It can be made of ordinary paper sealed with gum at but little expense and easily packed in large quantities for trans portation.

Other ways of constructing this cup will. occur to those skilled in the art, the main. feature and novelty being the folding; over of the part from which one is to drink so as to form a double edge and providing a continuation of this edge at each end thereof such as to hold the water from spilling out when the edge is in use. The cutting away of the side has not the only advantage as stated above. in that it prevents the side ll from touching the user of the cup and at the same time its ends prevent leakage of water at the ends of tie edge a, but it also exposes the inner port )ll of too side A. so that when it is desired the cup for use the top edge of th may be grasped by the thumb of one hand and the side edges squeezed together hy the other hand.

What claim as my intention A tulmlar, flexible. paper d cup niade from a single sheet of pa e tie law opposite edges or which overlap and are ed tube, one

gunnned together form. a fiat said tube being closed at one e d.

of open end having cur whereby the opposite edge of said open end will be exposed and may be utilized to open the cup from its flattened position the ends of said curved edge serving as side walls for said cup when in use and said opposite portion having a straight edge and being of double thickness whereby said edge may be applied to the mouth without danger of cutting the lip, the longest portion of said recessed side being equal in length to the 10 opposite side whereby when in use the liquid will be confined and directed to the mouth.
